Abstract

This research aims to determine the effect of using Canva-based video learning media on the mathematical problem solving abilities of class XII students at SMA Negeri 1 Air Joman. This type of research is quasi-experimental with a two-group pretest and posttest research design. The population in this study were all students of class XII Science consisting of 3 classes. The research samples used were 2 classes (Class XII IPA-2 and XII IPA-3) with 30 students in each class. In class XII IPA-3 was an experimental class using Canva-based learning video media and in class XII-2 as a control class without using Canva-based learning video media. After the learning was completed, a posttest was obtained with an average result for the experimental class of 80.5 and the control class of 76.4. The t-test results obtained t_count (3.774)> t_table (2.001). H_a is accepted, thus there is a positive and significant influence in the use of Canva-based video learning media on the mathematical problem-solving abilities of class XII students at SMA Negeri 1 Air Joman.

Abstract

This community service activity aims to increase awareness and understanding regarding bullying prevention at MTs Alwasliyah Sei Kepayang Tengah through the "Stop Bullying" outreach program. With an educational approach, this activity involves students, teachers and parents to understand the types of bullying, its impact and prevention strategies that can be implemented. This program was designed using participatory methods. The results of the activity showed an increase in participants' understanding, where knowledge about bullying increased from 35% to 88%. Teachers also show better abilities in detecting and handling bullying cases. Apart from that, this program succeeded in forming an Anti-Bullying Team as a sustainable effort to create a conducive school environment. In conclusion, this education-based collaborative approach is effective in preventing bullying and can be a model for other schools.

Abstract

Abstract: The aim of this research is to determine the effect of the Treffinger model assisted by a web live worksheet on the mathematical problem solving abilities of class VIII UPTD students at SMP Negeri 1 Kisaran for the 2023/2024 academic year. This research is experimental research with a Pretest-Posttest Control Group Design research design. The population in this study were all class VIII students at UPTD SMP Negeri 1 Kisaran. Two classes were selected using purposive sampling to be used as research samples. Class VIII-1 as an experimental class is taught using the Treffinger model with the help of a web live worksheet, while class VIII-2 is a control class taught using a direct learning model. The data obtained in this research were in the form of students' mathematical problem solving ability scores which were analyzed using the t-test. Based on the data obtained on students' mathematical problem solving abilities, it is known that the average value of experimental class students' mathematical problem solving abilities is 83.67, which is greater than that of the control class, 73.67. From the results of the hypothesis test calculations, it is obtained that t_count>t_table is 4.94 > 1.67, so H_0 is rejected and H_1 is accepted. Based on the results of data analysis, it was found that there was an influence of the Treffinger model assisted by web live worksheet on students' mathematical problem solving abilities at UPTD SMP Negeri 1 Kisaran. Keywords: Treffinger Model; Web Liveworksheet; Mathematical Problem Solving Ability Abstrak: Tujuan penelitian ini  adalah untuk mengetahui pengaruh model Treffinger berbantuan web liveworksheet terhadap kemampuan pemecahan masalah matematis siswa  kelas VIII UPTD SMP Negeri 1 Kisaran tahun ajaran 2023/2024. Penelitian ini merupakan penelitian eksperimen dengan desain penelitian Pretest-Posttest Control Group Design. Populasi dalam penelitian ini adalah seluruh siswa kelas  VIII di UPTD SMP Negeri 1 Kisaran. Dua kelas dipilih secara purposive sampling untuk dijadikan sampel penelitian. Kelas VIII-1 sebagai kelas eksperimen yang diajarkan dengan menerapkan model Treffinger berbantuan web liveworksheet sedangkan kelas VIII-2 kelas kontrol diajarkan dengan model pembelajaran langsung. Data yang diperoleh dalam penelitian ini berupa skor kemampuan pemecahan masalah matematis siswa yang dianalisis dengan uji-t. Berdasarkan data kemampuan pemecahan masalah matematis siswa yang telah diperoleh, diketahui bahwa rata-rata nilai kemampuan pemecahan masalah matematis siswa kelas eksperimen sebesar 83,67 lebih besar dari kelas kontrol 73,67. Dari hasil perhitungan uji hipotesis diperoleh t_hitung>t_tabel yaitu  sebesar 4,94 > 1,67 maka H_0 ditolak dan H_1 diterima. Berdasarkan hasil analisis data diperoleh bahwa ada pengaruh model  Treffinger berbantuan web liveworksheet terhadap kemampuan pemecahan masalah matematis siswa di UPTD SMP Negeri 1 Kisaran. Kata kunci: Model Treffinger; Web Liveworksheet; Kemampuan Pemecahan Masalah Matematis

Abstract

Abstract: This study aims to examine the effect of the cooperative learning model Numbered Heads Together (NHT) assisted by YouTube Education on students’ mathematical conceptual understanding in Grade X at SMA Negeri 1 Air Joman. A quantitative approach with a quasi-experimental design was used, involving two groups: an experimental class and a control class. The data were found to be normally distributed and homogeneous. Valid and reliable instruments were used. Results show a significant difference, with the experimental group achieving a higher average score are 17.04 compared to the control group are 11.68 indicating that the NHT model with YouTube support enhances students’ conceptual understanding. Keyword: Numbered Heads Together; YouTube Education; mathematical conceptual understanding. Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe Numbered Heads Together (NHT) berbantuan aplikasi YouTube Education terhadap pemahaman konsep matematis siswa kelas X di SMA Negeri 1 Air Joman.
